Implement SHA-256 abstraction
The Large File Storage extension specified by GitHub [1] uses SHA-256 to compute the ID of large files stored by the extension. Hence implement a SHA-256 abstraction similar to the SHA-1 abstraction used by JGit. [1] https://git-lfs.github.com/ Bug: 470333 Change-Id: I3a95954543c8570d73929e55f4a884b55dbf1b7a Signed-off-by: Matthias Sohn <matthias.sohn@sap.com>
